摘要:
The present invention relates to a glass sheet having an amount of fluorine contained in the glass of more than 0.23 mol %·μm and 21 mol %·μm or less on a depth-direction profile by secondary ion mass spectrometry (SIMS) in which a horizontal axis expresses depth and a vertical axis expresses fluorine concentration (mol %). According to the glass sheet of the present invention, warpage after chemical strengthening can be reduced and polishing treatment or the like before the chemical strengthening can be simplified or omitted.

摘要:
A glass sheet has one surface and the other surface facing the one surface in a thickness direction, wherein a fluorine concentration (average fluorine concentration by SIMS at a depth of 1 to 24 μm) in the one surface is higher than that in the other surface. The following expression is satisfied: 0.07≦ΔF/ΔH2O. ΔF (mol %) is a value obtained by subtracting an average fluorine concentration in the surface having the lower fluorine concentration from that in the surface having the higher fluorine concentration, and ΔH2O (mol %) is an absolute value of a value obtained by subtracting an average H2O concentration in the surface having the higher fluorine concentration from that in the surface having the lower fluorine concentration.

摘要:
A method for manufacturing a float glass includes a step of melting a glass raw material, a step of forming the glass melted in the melting step into a glass ribbon while floating the glass on a molten metal, and a step of annealing the glass ribbon. In the forming step, a gas or a liquid containing a molecule having a fluorine atom present therein is blown to the glass ribbon having a viscosity of from 1.0×104 to 2.5×1010 Pa·s.
摘要:
An object of the present invention is to provide a glass sheet in which warpage after chemical strengthening can be effectively suppressed and also polishing treatment or the like before chemical strengthening can be omitted or simplified. Thus, the present invention provides a glass sheet in which a surface Na2O amount in one surface thereof is lower than the surface Na2O amount in the other surface by 0.38% by mass to 1.2% by mass.
